In 1984, the stations were acquired by CHEZ-FM Inc., the owner of Ottawa's CHEZ. In 1986, CKUE changed its callsign to CHEQ, and adopted the Q101 brand.
In 1999, the CHEZ group of stations were acquired by Rogers Communications. At the end of the year, Rogers converted the station to a modern rock format, using the callsign CIOX and the brand name Xfm. The station's facilities were moved into Ottawa, and in 2001, the CRTC found that by operating CIOX as an Ottawa station, Rogers was in contravention of market concentration rules about the number of radio stations in a single market that can be owned by the same company. As a result, the CRTC ordered Rogers to return the station to Smiths Falls.
On January 9, 2004, the station adopted its current format when Rogers converted the former CKBY in Ottawa to the current CISS. 101.1 became CKBY, and 105.3 became CISS a month later after the format change.
